Prices in the US will probably be easier to swallow. Here in the EU
prices are simply hilarious. Here's a dutch site that offers at 10k:
http://www.dewatersportwinkel.nl/Watermakers/184-713/Watermaker-
Spectra-Catalina-CT-300-MPC/Catalina-300-watermakers/
I saw the 150 model somewhere else for roughly the same.
Would be nice to know about US prices but I guess you'll also need a
stiff drink after you hear or read it.
Another source: Brent Swain describes his self built watermaker in
his book: Origami Metal boatbuilding. (I don't have the book myself,
I'm not related whatsoever, I just read his comments on
cruisersforum.com):

He built his watermaker using a general 3GPM pressure washer pump
model#tt9111 with ceramic plungers ($325 CDN). As most 540 gallon a
day membranes have been stadardised and fit a sch 40 2 1/2 inch
stainless pipe he built even his own pressure housing.
He spent $1,000 CDN in total. Reading that put the normal smile back
on my face again.. :-)
Before I really start purchasing and building, the fundamental
question is for me: how do I want to get a HP pump (Cat, General or
whatever) in motion. I guess it will have to be AC- or belt-driven.
That kind of load cannot be practically delt with using 12v motor...
Using the inverter and the frequency-regulator for a 3-phase 2,2 kW
motor seems like inefficient use of preciously generated Ah's... but
at the moment I am thinking in that direction. That way using the
diesel (or in our case the genset) for appr. an hour every 3-4 days
gives: a healthy load on your engine, a full watertank, pressurised
scuba tanks, and also puts serious amps into the batteries with the
regulator in the bulk-phase and after that you can use solar and
wind to continue the charging with 13,8 volts till batteries are as
full as they will get.
Cheers, Len.
P.s. If you are having difficulty to find the Good Old Boat issue
email me off list.
